Starcraft 2 in game item

I´ve recently recieved a mail from Blizz about the virtual ticket for blizzcon.
There they said that you would recieve deathy the deathwing murloc and a SC2 in game item, so anybody knows what the item is?

"Death will rise from the tide!" Level 80 Elite Tauren Chieftain once warned -- and at BlizzCon 2010, the band's dire musical prophecy will finally come to pass. Everyone who attends this year's BlizzCon or purchases the BlizzCon Virtual Ticket will receive an exclusive set of murlocalyptic in-game items for World of Warcraft and StarCraft II: Wings of Liberty. World of Warcraft players will be joined by Deathy, a murloc companion decked out as Deathwing and doing his best to strike fear into the hearts of Azeroth's crustacean population. You'll also be able to display your tidal pride in StarCraft II with a Murloc Marine character portrait and a pair of deep-sea decals to emblazon on your units, each with a different terran, protoss, and zerg design.
